The Cardiac Medicine Certification (CMC) exam is designed for certified nurses currently practicing in areas such as CCU, combined ICU/CCU, medical ICU, telemetry, progressive care, heart failure clinics/home care, interventional cardiology, cardiac catheterization labs and/or electrophysiology units.

Exam content: Since all eligible candidates must hold a clinical nursing specialty certification, the 90-item subspecialty exams concentrate solely on the Synergy Model component of Clinical Judgment. Although components such as patient teaching and collaboration are very important in providing patient care, eligibility for the CMC and CSC subspecialty credentials assumes that the nursing licensure exam and the clinical nursing specialty certification exam tested these elements.

The CMC exam is a total of 90 questions, with 15 of them not counting towards the final score. You've got two hours to take the exam. To pass the CMC, you must get at least 52 questions out of the score 75 questions correct.
